romeotuma wrote: Low IQ & Conservative Beliefs Linked to Prejudiceby Stephanie Pappas LiveScience January 26, 2012There's no gentle way to put it: People who give in to racism and prejudice may simply be dumb, according to a new study that is bound to stir public controversy... I've heard it said that people who support conservatives are one S or the other: Stupid or Solvent. Maybe. I think it's more like ignorance. For example, my uncle was a jailhouse cop in Cleveland, and he hated black people, because all he saw were the very dregs of society.

You got the joke wrong.
"Neutrino steps up to the bar.
Bartender can't see him yet, so neutrino, thinking he's being ignored, leaves in a huff (at 1.8c).
Bartender then says, "we don't serve neutrinos here", and everybody laughs at the bartender because the neutrino had already left."
Ideally you should have posted this before beaker posted the joke.

Lazy8 wrote: oldslabsides wrote:now wait a minute...What if this were filmed from above the trombone? Or from beneath; would the "shockwave" still be in the shape of an arc? Something about the perspective here just doesn't seem real to me. Yes. Shockwaves are a finite thickness, and what you see is the light bending as it passes thru the shockwave. From the side the light passes thru more of the shockwave along the leading surface of the shock than is does behind the leading surface on its way to you, so you see it in profile. Here's a way to think about it that might help: hold an imaginary half of a pumpkin in your hand with the guts all scooped out. It's a pretty much a uniform thickness. Now imagine you have a long pumpkin-carving knife you can poke thru the pumpkin, and poke it thru near the open end of the pumpkin, all the way across. It goes thru nearly perpendicular to the outer surface, which penetrates nearly the minimum amount of pumpkin possible while still getting thru both sides. Now poke it thru sideways across the bottom of the pumpkin. Since it goes thru the wall at a shallower angle it goes thru more pumpkin on its way out the other side. Poke it thru low enough and its whole trip thru will be inside the wall of the pumpkin. A ray of light taking that path will see the maximum amount of distortion from the differential index of refraction of the shock wave—not because it spent more time in the different index, but because it had farther to go before its path straightened out again when it reached undisturbed air on the other side. So rays of light along the leading surface of the shock will appear to show it in cross-section. This made my face hurt.
